Dry eyes

If your eyes feel constantly dry or gritty, they may need treatment. Your eyes might be dry because you are not making enough tears, your tears are evaporating too quickly, or you don't blink normally.

If your eyes become too dry you are more likely to get serious infections, scarring and thinning of your corneas, or even holes (perforations) in your corneas. In rare cases, you could lose your sight, or even an eye.

If your eyes are dry because you're not making enough tears, this is called keratoconjunctivitis sicca (ker-a-toe-con-junk-ti-vi-tis sicca) or sicca syndrome.
